Hello vamsi426!
You can read here how to create a histogram in this article:
https://www.highcharts.com/docs/chart-a ... -histogram
You can add your data as
scatter and then set its
visible property to false. After that, you can create a histogram based on this data and use a
binsNumberproperty. To add
bellcurve and
histogram based on one series you should also assign them to separate axes. Check out the demo below to see an example based on the demo you provided.

Feel free to ask any further questions.
Kind regards!
